8 Trendy Workouts (Ranked on the Sweat-O-Meter Scale)

Sometimes you want to walk out of the gym drenched in sweat, and sometimes you want to keep that spendy blowout intact. That's where this sweat-o-meter comes in

Equinox's Animal Flow: 6.5 When you take your first Animal Flow class, you'll feel a little ridiculous. You hop like a frog, swing your arms like a monkey -- you get the idea. All of the movements are inspired by animals in the wild -- with a dash of breakdancing and martial arts for good measure. You'll get sweaty to the point where you'll definitely want to take a shower. But hair washing could go either way depending on how much your scalp sweats and whether you have dry shampoo in your gym bag.

Try it: If you have room at home, download the digital video or order the DVD. If you'd prefer to try it in a gym, Equinox offers classes across the country.

This article could have been written for me. Last year, I exercised daily (either on my stationery bike or walking the track at the high school), but I HAD to wash my hair every day. That stripped it of color and made already-dry locks more vulnerable. I had nearly (nearly) forgotten that there are other things I can do--such as ballet moves--where I won't be a soaking mess! Great piece!
